50异丙甲草胺·莠去津悬浮乳剂防除高粱田杂草药效评价

摘要

为进一步探索50%异丙甲草胺·莠去津悬浮乳剂对高粱田杂草的防除效果及对高粱生长的安全性,2016年在林甸县工农村进行了高粱播后苗前土壤封闭处理试验.结果表明:在高粱播后苗前土壤封闭喷施50%异丙甲草胺·莠去津悬浮乳剂制剂,用量2 250~3 000 g·hm-2,对一年生杂草稗草、狗尾草、藜、反枝苋、酸模叶蓼等均具有较好的防除效果,控草时间长达50 d以上,且对高粱生长安全.%In order to further explore the control effect and safety of 50% metolachlor·atrazine suspension emulsion on sorghum weeds,the soil sealing treatment of sorghum before seeding and after sowing was carried out in Gongnong village of Lindian county in 2016.The results showed that 50% metolachlor·atrazine suspension emulsion at 2 250~3 000 g·hm-2was sprayed before seeding and after sowing,which had a good control effect for annual grass such as Echinochloa crusgalli,Setaria viridis,Chenopodium album,Amaranthus retroflexus and Polygonum lapathifolium Linn,etc.,and control grass time was up to 50 days or more.It was safe to growth of sorghum.
